Carbohydrates, fats, and proteins can all be used as the fuel, but it is most useful to  consider glucose. C 6 H 12 O 6  + 6O 2    6CO 2  + 6H 2 O + Energy (ATP + heat) The catabolism of glucose is exergonic with a   G of −686 kcal per mole of glucose. Some of this energy is used to produce ATP, which can perform cellular work. Redox reactions release energy when electrons move closer to electronegative atoms. Catabolic pathways transfer the electrons stored in food molecules, releasing energy that is  used to synthesize ATP. Reactions that result in the transfer of one or more electrons from one reactant to another  are oxidation-reduction reactions, or  redox reactions. The loss of electrons is called  oxidation. The addition of electrons is called  reduction. The formation of table salt from sodium and chloride is a redox reaction. Na + Cl
